What are the options for talking about portable monitors? As the performance of computers continues to increase, the speed of development is also striding forward. Our attention to computer hardware is getting lower and lower, but the interest in portable electronic products is not diminished. Interest in convenient and convenient peripherals is becoming more and more important. Then, let's talk about the skills of choosing a portable display.

Select skill dimension 1: panel

The first thing to buy a portable monitor is to look at it? Yes, it is to look at the panel of the display. For now, the display mainly stays in the LED stage. The CCFL has already withdrawn from the market, and the OLED is not yet mature. There are three types of LED panels on the market: TN, VA and IPS. It is Samsung's PLS, but PLS is based on IPS.

Choice Tip Dimension 2: Color Gamut

The gamut is one of the indicators for measuring the color performance of a display, but not all, because there is a color deviation value, we will talk about it below. At present, there are mainly four color gamuts of the display, sRGB, DCI-P3, Adobe RGB, and NTSC. Their relationship is roughly as follows (based on 100% NTSC)

Choice Skill Dimension 3: Color Deviation Value

Another color metric outside the gamut is the color deviation value. Usually you will see △E<X on the display page of the display, which is the color deviation value, also called color difference. The lower the X, the more accurate the display color.

Choice Tip Dimension 4: Interface

Let's talk about the interface problem. In fact, with the development of time, DVI and VGA are already in the category of elimination. Because the former is huge, the double chain can only run 2560*1440@60Hz, and the latter shows the effect is worrying. Therefore, when purchasing a monitor, it is recommended to use HDMI and DP as the standard. If you have more devices to connect to the monitor, then it is recommended that the monitor has more interfaces, so that it is not enough.

Choice Tip Dimension 5: Refresh Rate & Response Speed

Refresh rate I think I should not need to say more, as long as the display is not lower than the 60Hz refresh rate, it is not a good thing, of course, people who have used the 144Hz refresh rate monitor did not see this sentence. The 30Hz pit LED display is currently barely visible.

Choose skill dimension 6: G-Sync/free sync, HDR, etc.

Finally, let's talk about this problem. We all know that there are two main types of display synchronization technologies, one is NV G-sync, and AMD's free sync, both of which can synchronize the display refresh rate with the current frame number. Avoid the tearing of the picture, the difference is that NV is hardware level and closed, AMD is software level and authorized to open, but it can only be used for A card, so G-sync display is often more expensive than Free sync display. More than 1000, not to say that the manufacturer is black, but the licensing fee and price of the NV chip is really too high. As for Free Sync, although only A card uses this restriction, it is said that inserting an A card into the computer can bypass this limitation, and the AN mixed fire can.

So what should I do when I buy a portable monitor? If it is a low-end display, don't expect too much coverage of the gamut value, because the low-end display is not too much, if you are willing to spend money, strictly follow the sRGB color gamut of 100% or 99%. The display is preferred because it shows the "most accurate" color for most people. If you are interested in color, 100% RGB is your best choice, and the price is scary 233. But many people think that the color of the portable display is too bright, just like the mobile phone that looks at the OLED screen. The P3 color gamut is mainly used by Apple. It is not mentioned here. As for the VA screen display, it will write itself as a wide color gamut display with 100% NTSC or above, but the actual color accuracy is very worrying. It is not recommended here.
